A comparative study of the effects of the fungus, Neocallimastrix frontalis, a coculture of Syntrophococcus sucromutans and Eubacterium oxidoreducens, and a mixed culture of these three microorganisms on 14C-lignin-labeled cell walls of wheat reveals that lignin solubility by the two bacteria is lower than that by the fungus. Degradation of phenolics by the two bacteria is higher than that by the fungus. S. sucromutans produces labeled acetate by O-demethylating (O-methyl-14C)syringyl lignins.

Are bacteria omnipresent on Phanerochaete chrysosporium burdsall?

Article Abstract:

A study on bacterial omnipresence on Phanerochaete chrysosporium burdsall was conducted to confirm viable bacterial strains that could be recovered .The polymerase chain reaction (PCR) amplication of ribosomal RNA was performed to associate fungal cultures to bacteria. Results suggest that with PCR primers related to small-subunit rRNA genes, no bacterium-like product could be amplified from P. chrysosporium strain.

Effects of coumarin and sparteine on attachment to cellulose and cellulolysis by Neocallimastix frontalis RE1

Article Abstract:

Coumarin and sparteine, plant secondary metabolites, decrease the attachment to cellulose in the fermentation products of the anaerobic fungus Neocallimastix frontalis RE1. Coumarin and sparteine also reduce cellulose solubilization and the proportion of lactate in the fermentation products. However, none of them directly inhibits the endoglucanase or lactate dehydrogenase activities of the fungus cell extracts.
